background: a successful malaria elimination program calls for enough attention to parasite carri­ers, especially asymptomatic malaria, as well as the diagnosis and treatment of clinical cases. asymptomatic malaria is an infection that patients do not show any symptom; thus, these patients play critical role in the concept of an elimination program. the current investigation was con­ducted to e...

background: in this study, quantitative 32p bremsstrahlung planar and spect imaging and consequent dose assessment were carried out as a comprehensive phantom study to define an appropriate method for accurate dosimetry in clinical practice. materials and methods: ct, planar and spect bremsstrahlung images of jaszczak phantom containing a known activity of 32p were acquired. in addition, phanto...

background: spermatogonial stem cells (sscs), a subset of undifferentiated type a spermatogonia, are the foundation of complex process of spermatogenesis and could be propagated in vitro culture conditions for long time for germ cell transplantation and fertility preservation. objective: the aim of this study was in vitro propagation of human spermatogonial stem cells (sscs) and improvement of ...

background: apical membrane antigen 1 (ama-1) is positioned on the surface of merozoite and it may play a role in attack to red blood cells. the mainaim of present study was to determine the genetic variation, as well as, to detect of selection at domain i of ama-1 gene plasmodium vivax isolates in iran. methods: blood samples were collected from 58 patients positive for p. vivax ,mono infectio...

background and objective: parkinson's disease (pd) is an age-related neurodegenerative disease with selective damage of dopaminergic neurons of the mesencephalon. l-dihydroxyphenylamine (l-dopa) therapy is currently the gold standard maneuver for pd. due to the protective, anti-inflammatory, and antioxidant effect of sesamin, this study was undertaken to assess dose-dependent effect of this age...

multiple sclerosis (ms) and its animal model, experimental autoimmune encephalomyelitis (eae), are inflammatory autoimmune diseases of the central nervous system. chymotrypsin is a serine protease with immunomodulatory effect in the peripheral organs. we previously demonstrated the immunomodulatory effect of chymotrypsin in ameliorating the eae in female lewis rats. however, there are sex-based...

objective(s):blactx-mand blaper are two genes that encode class a extended-spectrum β-lactamases (esbls) and can be responsible for therapeutic problems. this study was carried out to evaluate the molecular properties of these genes in clinical isolates of enterobacteriaceae by polymerase chain reaction (pcr), restriction digestion and sequencing. materials and methods: during six months, start...
